DOCKAGE TESTER.

Application filed January 25, 1926. Serial No. 83,548.

My present invention provides a device especially designed and particularly adapted for use a dockage or sample tester, and generally stated, it consists of the novel devices, combinations of devices and arrangements of parts hereinafter described and delined in the claims.

An extremely simple and highly efiicient form of this improved separator or dockage tester is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

-. Fig. 1.

In this preferred arrangement of themachine, I employ an inclined separating plate provided with pockets adapted to receive certain kinds of materials, such as wheat, but to reject other kinds of grain, such as oats, barley, and the like; and this plate is mounted on a vibratory supporting bed. The said supporting bed maytake various forms, but as shown, it is made up of an inclined plate 3 with depending side flanges or boards secured to the upper ends of four.

upright resilient or spring metal supporting legs 5, which latter, at their lower ends, are anchored by screws 6 or v other suitable devices to a floor 7 or other fixed structure.

The separating plate 8 is formed with quite closely positioned pockets 9, which, for the separation of wheat from oats, will be of suchsize that they will receive the wheat but will not completely receive nor hold the longer grains, such as oats and barley. This pocketed separating plate rests on the supporting bed plate 3 and, hence, will be carried in an inclined position. Secured to and'depending from the lower end of the separating plate 8 are hinge lugs 10 formed with open seats or notches 11 that pivotally and detachably engage a pivot or hinge rod 12 rigidly secured to and extended between lugs 18 on the bottom of the lowerv end of the bed plate 8. By reference particularly to Fig. 2, it will be noted that the bed plate 3 is notched at let to clear the lugs 10. Also, it will be noted that the bed plate 3, at its upper edge and at its sides, is formed with an upstanding retaining flange 15 within which the upper and end side portions of the separating plate 8 areseated. The sepa rating plate 8. is formed at its side-edges with upstanding flanges 16 that are increased. n depth at their upper ends so that they form the sides of a receiving hopper 17 located the upper or. receiving end of said separating plate. The front plate of this hopper 17 is spaced from the separating plate so as to afford a feed passage 18 through which the commingled stock will be delivered onto the pocketed portion of the separating plate. I

To produce a flow of the commingled stock downward over thepocket surface of the separat ngplate, vibratory movement of the latter is. required, and this. may be best accomplished by vibrating the supporting bed. Of .course,'such vibratory motion may be produced by any suitable mechanism or means but, as shown, is arranged to'be produced by a power device shown onlyjin Fig. 1 andwhich power device involves a shaft 19 journaled' in suitabl fixed bearings 20 and provided atone end with an eccentric wrist pin or crank 21 connected by a link 22 to a bracketj23 rigidly secured to one side plate 4 of the vibratory supporting bed. On 7 the shaft 19 is a pulley 241 over which, as

shown, 'runs a power-driven belt 25. The upper plate or side of the hopper 17 is shown as provided with a projecting hand piece 27 by means of which the separator may be readily moved on the pivot rod 12 from its operative position shown by full lines into its discharged position shown by dotted lines in Fig.2. The numeral 27 indicates a receptacle located in the discharge end of the separating plate 8.

The dockage tester may be usedin a num ber of difierent ways and for different kinds of separations, depending upon the size of.

the pockets in the separating plate.v For the present illustration, assume that the pockets in the separating plate are of such size and depth that they will receive and hold wheat kernels lodged therein but will reject or, at

any rate, will not permanently hold the l longer grains, such as oats and barley. Then, assume that the device'is to be used to primarily separate the wheat and smaller seeds from the cats and barley. The commingled stock, assumed to consist of wheat, oats, barley and bad or small seeds, which are usually designated as dockage, will be placed in'the hopper 17. This commingled stock Will runpermanently lodged in the pockets but Will be rejected thereby and will finally be shaken oil from the lower end of the separating plate, While the WllQElt' and small seeds or dockage will-"be caught and retained in the pocl'tets. V

If a receptacle 27 be placed below the lowor end" of the s'e'paratii'ig plate, the rejected oats and barley Will beprecipitated into the same; Then another receptacle may be placed in position below the, delivery end of separating plate and then if the separating plate be turned intd an upright position, as indicated by dotted lines in Fig. 2, the materials lodged in the pockets 9, to wit: the Wheat and smaller gra-in's'or seeds,-1o'r, in other words; tlie docltage, will be discharged from the separating plate and into such receptacle The separation of the dockage from the good-Wheat ma then be per-- formed the use'of aseparating plate having smaller'pocket's t liat'is,-pockets of'such smaller-sizethan that of the plate just above described that'tlieywould receive and hold the dbckage er seedssmal'lerthan Wheat and will not permanently hold but Will reject the Wheat, so that the latteravill discharged on from the lower end of the separating plate under vibration 7 thereof, -w-hile the dockag'e will be held in the pockets and may subsequently be discharged into 'a'suitable receptacle when the separating plate is turned into an upright position.

From What hasbeen said, it is obvious that by the use of separating plates having pockets of the appropriate sizes, various different kinds of separations of grains, seeds or like materials may be very effectually accomplished;

As a further illustration of the use of the 1 dockage tester or separator, it may be used to separate broken kernels from'whole kernels of rice, or for theseparation of broken kernels of any kind of grain frointhe Wholekernels.

The device described illustrates very 7 simple embodiment of theinvention, but it will, of course, be understood that various modifications thereof may be made, all Within the spirit of the invention herein (lisclosed and claimed.
